About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556511021. Listed at 21 retailers as of November 5, 2026, with prices from HK$14,679 to HK$41,483, a HK$26,804 spread on the same certified stone. NZ Jewellers lists it at HK$41,483. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
